Question 1
Power ElectronicsSingle-Phase Controlled Rectifiers

For a single-phase half-wave controlled rectifier with a resistive load, the SCR conducts from firing angle alpha to?

  • Api radians
  • B2pi radians in every case
  • Calpha/2
  • Dpi/2 regardless of alpha
Report an error
Correct Answer: A. pi radians
Explanation: With a resistive load, current follows voltage and becomes zero at the supply zero crossing at omega t=pi.
